1 Claim.

The present invention relates to closures for containers of the mixing and shaker type, and has for an object to provide a cap with a pouring spout and a relatively large opening through which various ingredients may be introduced, and which also has a cut-off or valve for closing and controlling the spout and the said opening.

Caps for cocktail mixers or shakers must fit tightly and are frequently made of silver and other expensive metals and must be made with a fair amount of precision in order to provide the necessary tight fit and prevent spilling the contents of the glass or other container used. When these caps are frequently removed and replaced they gradually lose shape and become worn so that the frictional engagement between the cap and the container is lost with the disadvantage that the caps leak and do not stay in place.

One of the purposes of this invention is to provide a cap which does not have to be repeatedly removed and replaced for pouring and for introducing the various ingredients of the drink but which maybe operated to provide an opening of adequate size through the cap to receive the ingredients without removing the cap and which may be adjusted to open a spout and provide a screened opening therethrough or an opening which is free and unimpeded.

Another object of thisinvention is to provide a cap having the above characteristics but which may present a relatively smooth and uninterrupted exterior contour susceptible of aesthetic treatment without knobs, handles or other projections other than the spout and which at the same time provides a relatively simple and economical structure readily cleansed and not easily gotten out of order.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a side elevation of a cap or closure in open position and constructed according to the present invention and as applied to the up per end of a container.

Figure 2 is a top plan view of the same, parts being broken away to show the interior structure.

Figure 3 is a vertical section through the closure on the line 33 of Figure 2.

Figure 4 is a top plan view of the closure with the spout closed and the ingredient opening partly closed.

Figure 5 is a transverse section through the closure taken on the line 5--5 of Figure 2.

Figure 6 is a transverse section, on a reduced scale, through the upper end of a receptacle showing a modified form of cap mounted thereon and embodying the features of the present invention.

Figure 7 is a top plan view of the same, and

Figure 8 is a view similar to Figure 6, but showing a further slight modification thereof.

Referring now to the drawing, l0 designates the upper portion of a receptacle which may be of glass or other suitable material and upon which the cap or closure of this invention is adapted to be fitted.

The body portion of the cap may be made from sheet metal spun or otherwise constructed to shape and is shown in the present instance as having a dome shape top wall II with 21, marginal annular shoulder l2 terminating in a depending flange or skirt I3. The lower end of the flange I3 is adapted to embrace the upper end of the container Ill with a tight frictional grip for holding the cap to the container and sealing the joint therebetween. The flange i3 is provided with a stop shoulder or seat 14 to engage the upper edge of the open top of the container ID and limit the downward movement of the cap thereon and assist in effecting the desired seal of the joint. This seat M may be formed by providing an annular inwardly pressed bead 15 intermediate the upper and lower ends of the flange I3, and the bead l5 also increases the strength of the cap and further provides an exterior groove on the flanges 13 for attachment of a valve element as will later be described.

The dome Wall or top H of the cap has at one side, which may be termed the rear side, an opening [6 through which ingredients to be mixed may be introduced into the container I0, and this opening l6 may be of any desired size or shape for the purpose. The opening It also serves as a vent for the cap during pouring.

The other or front side of the cap has one or more slots or openings i'l located in the upper part of the flange l3 and extending circumferentially thereof and through any one of which the contents of the container I0 may be poured with out removing the cap. As shown there are two spaced slots H in the flange l3 and one of these slots may be provided with a screen or strainer l8 if desired so that the pouring may take place through the strainer 18 or through the free opening of the other slot [1.

The valve element [9 of the cap is of dome shape and of annular form and may comprise spun sheet metal and rotatably fits over the dome ll of the cap body. The marginal edge of the valve dome l9 has an annular rim 20 which seats on the shoulder [2 of the cap and has a depending flange 2| which extends about the upper part of the cap flange I3 and is peened or turned in at its lower edge into the groove of the bead l5 so as to hold the valve element for rotation on the cap body.

This valve flange 2| has a pouring opening or slot 22 at one side, the front side, adapted to register with the one or more pouring openings I1 of the cap body. The opening 22 may be defined within a spout 23 outstanding from the valve flange 2| so that the spout 23 is carried upon and turns with the valve element. The dome l9 of the valve element has an opening 24 in its rear side opposite the spout 23 which may conform in size and shape to the dome opening H5 in the cap body. The openings l6 and 24 are so relatively located in their respective cap body and valve element as to register more or less when the spout 23 is in register with the one or more pouring openings l1 in the cap body. The cap is thus well vented both during the filling of the receptacle l0 through the dome openings l6 and 24 and during pouring of the contents of the receptacle through the spout 23. By a slight turning adjustment of the valve element the strainer l8 may be brought opposite the spout 23 so that the mixture may be strained during pouring.

While, of course, the invention is susceptible to considerable modification, Figure 6 shows one such modification wherein the container l0 carries a cap body 25, which, like the cap body of the preferred form, has the seating and holding flange [3 to fit snugly over the upper end of the container 10 so as to seal the cap on the container.

The dome 26 of the cap is provided at its rear side with an arcuate opening 21, and the cap 25 is provided at its forward side with a spout 28 which opens into the cap and through which the contents of the container It! may be poured. A valve part 29, which is shaped to the general configuration of the upper portion of the cap 25, is fitted against the interior of the dome 26 and has a depending flange 30 which normally closes the inner end of the spout 28 and which, as shown in the preferred form, has suitable openings to be brought into register with the spout 28 to open the same when the valve part 29 is turned. A knob 3| extends above the cap 25 at its central portion and is freely rotatable in the dome 2B, but is fixed at its lower end to the valve part 29, so that by turning the knob 3| the valve part 29 may be turned or rotated within the cap 25. To determine the open and closed position of the valve part 29, the dome of the valve part is provided with a stop pin 32 disposed at the rear portion of the valve 29 and which projects into the arcuate slot 21 of the cap dome to engage the marginal edge of the slot 21 at opposite ends thereof, such as shown in Figure 7.

Figure 8 shows a slight modification in the form of Figures 6 and '7 wherein the valve part 29 is pivotally and axially connected to the dome 26 of the cap 25 by a rivet, eyelet, or other suitable pivot 33, and a knob 34 is mounted on the rear portion of the dome of the valve part 29 and projects upwardly through the slot 21 to provide not only an actuating element but a stop for engaging the opposite ends of the slot 21. The knob 34 is grasped and swung about the pivot 33 to turn the valve 29 and thus open and close the spout 28.

It will be also noted that the valve 29 is provided in its dome portion with a slot or opening 35 which corresponds substantially to the slot 21 and which is brought into more or less register therewith when the valve 29 is turned to open the spout, so that the opening through the top of the cap is opened for venting the cap for the introduction of ingredients to be mixed in the container l0 without removing the cap therefrom.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modiflcations being restricted only by the scope of the following claim.

What is claimed is:-

A beverage shaker cap for a receptacle having an open top, comprising a cap body including a top having a relatively large filler opening at one side of the axial center thereof and an annular side wall, a rib dividing said side wall into upper and lower portions, said lower portion constituting a flange engageable about the upper edge of the receptacle and said rib limiting the insertion of the cap on the receptacle, said upper portion having a pair of spaced apart discharge openings opposed to said flller opening and an annular groove below said openings, a screen element for one of said discharge openings, a valve element engaging over the top of the cap body and provided with a filler opening for registry with the filler opening of the cap body, an annular flange carried by said valve element and enclosing said upper side wall portion, said flange having an inturned lower edge engaging in said groove to rotatably mount said valve element on the cap body, and a pouring spout carried by the flange of said valve element opposite from the filler opening thereof.
